LATHERER FOR SOAP mourn Filed June 9, 1972 I 2 Sheet-8heet 2 UnitedStates Patent US. Cl. 252-359 E 2 Claims ABSTRACT OF THE DISCLOSURE Alatherer for a liquid soap is disclosed. The latherer includes a casingfor accommodating the mechanism of the latherer therewithin. A nozzle ismounted on the casing at the upper opening thereof. In the casing astirring chamber is located and the stirring chamber accommodates arotor having a blade for stirring a liquid soap. A motor for driving therotor and a tank for supplying a soap liquid are mounted on the casing.The tank communicates with the stirring chamber through a passage. Avalve is provided within the passage and a switch is provided on thecasing the switch being adapted to open and close the valve.

The present invention relates to a handy latherer, more particularly toa latherer for stirring soap liquid to form creamlike soapsuds which mayspout therefrom.

A first object of the present invention is to provide a latherer bywhich it is feasible to lather a required quantity of soap liquidthoroughly.

A second object of the present invention is to provide a latherer withwhich soapsuds may be obtained easily and the body of which may bereadily held and maneuvered.

These and other objects are accomplished by the parts, improvements,combinations and arrangements comprising the present invention, apreferred embodiment of which is shown by way of example in theaccompanying drawings, and hereinafter described in detail.

In the drawings, FIG. 1 is a vertical section of the latherer accordingto the present invention.

FIG. 2 is a section of the part of the stirring chamber showing therelation between the switch and the valve and the condition beforepushing the switch.

FIG. 3 is the same section as FIG. 2 but shows the condition afterpushing the switch is shown.

FIG. 4 is a plan view of FIG. 2.

In the drawing, A is the latherer. An upper casing 1, is provided at theupper portion of the latherer. A nozzle 2 is attached to the upperportion of the casing 1, said nozzle 2 having a nozzle hole 3 having anelliptic crosssection. The edge 4 of the nozzle hole 3 forms a concavesurface as shown.

The upper end portion of the cylindrical wall 6 which forms stirringchamber 5, is positioned against the lower portion of the inner wall ofthe nozzle hole 3. An annular ridge 7 is provided on said cylindricalwall 6 and protrudes along the inner wall at the upper portion thereof.The inside of the cylindrical wall 6 forms a stirring chamber and withinthe stirring chamber 5 a cylindrical rotor 9 is provided. The rotor 9 isrotatably positioned coaxially within the stirring chamber 5. On theouter periphery of the rotor 9 a helical stirring blade 10 is formed anda uniform clearance 11 is left between the edge of the blade 10 and theinner periphery of the cylindrical wall 6. A small space is left betweenthe outer peripheral surface of the blade and the annular ridge 7 on thecylindrical wall 6. 12 is a shaft of the rotor 9 and the shaft 12 isconnected to the driving shaft of the motor 13 through the wall 8 at thelower end of the stirring chamber 5. The wall 8 maintains the bottom ofthe stirring chamber 5 in a liquid tight condition.

3,814,697 Patented June 4, 1974 The motor 13 is secured to the supportmember 14 fixed to the lower end of the upper casing 1, and cylindricalwall 6 is fixed to the wall 8 and also mounted securely on the supportmember 14 by means of bolts. 15 is a tank for soap liquid which isscrewed securely onto the lower end of the support member 14. The upperperiphery of the tank 15 is screwed onto the lower edge of the supportmember 14, and forms a liquid tight seal and on the lower centralportion thereof a valve box 16 is provided for injecting soap liquidthereinto, and said valve box is provided with a valve body 35 therein.17 is an inner cover covering the lower opening of the tank 15, theinner cover 17 being tightly and removably fitted to the lower edge ofthe tank 15.

A lower casing 18 is scewed onto the upper casing 1, and there is aslight separation between the inner periphery of said lower casing 18and the outer periphery of said tank 15. At the lower end of the lowercasing 18 a bottom cover 19 is removably screwed onto the screw threadprovided on the outer periphery at the lower end portion of the tank 15.An electric cord 20 depends from the bottom cover 19.

On the cylindrical wall 6 defining the stirring chamber 5 a soap liquidinlet 21 is provided. The inlet communicates with a hollow rod 23through a pipe 22 of a resilient material, the rod being slidablymounted and extend ing through the through-hole 26 provided on the wall8. The rod has a stopper 28 at the upper portion thereof consisting oftwo spaced rings and is adapted to slide in the through-hole of the wall8 by means of a lever 25 engaging said stopper 28.

A reservoir 29 is provided below the wall 8 and the reservoircommunicates with the tank 15 through a pipe 27. The reservoircommunicates with the rod 23 through a through-hole 30 provided on thelower portion of the rod when the rod is lowered by the lever 25 of theswitch 24.

Accordingly, to introduce soap liquid from the tank 15 into the stirringchamber 5, latherer A is first turned upside down to allow the liquid inthe tank to flow into the reservoir 29 through the pipe 27. Then, theswitch 24 is pushed against the spring 32 into the latherer and pivotsabout shaft 31. Since the spring 32 acts also as a terminal lead fromthe electric cord 20, when the switch 24 is depressed the spring 32 andthe other terminal 33 are brought into contact and the rotor 9 with thehelical blade 10 in the stirring chamber is thus activated and rotatedby the motor 13.

When the switch 24 is pushed further into the latherer, as shown in FIG.3, the end portion of the valve rod 23 is projected into the liquidreservoir 29 by means of the lever 25 of the switch engaged with thestopper 28, and the soap liquid in the tank flows into the stirringchamber through the pipe 27, the reservoir 29, the through-hole 30, thevalve rod 23, the pipe elbow 22 and the inlet 21, seriatim.

As shown in FIG. 1, the valve box 16 is mounted on the interior of anopening 34 of the tank 15 and said valve box includes a valve body 35and a ball 36, said valve body being slidably supported by thecylindrical wall of the lower opening 34 of said valve box, and thelower surface of said valve body being adapted to fit tight- 1y againstthe opening 34 in the state as shown in FIG. 1. A plurality of slits 37,38 are provided around the valve box and the cylindrical wall of thelower opening 34 respectively.

The latherer according to the present invention is constructed asmentioned above and when the latherer is used, bottom cover 19 isinitially removed from the body and the inner cover 17 engaged with thebottom cover 19 is also removed. Thereafter, the body is turned upsidedown and soap liquid is injected thru the opening 34 of the tank 15 bymeans of a soap liquid injection nozzle.

Valve body 35 is slidably fit within the opening 34, and when it ispushed by the injecting nozzle, the valve body 35 is slid slightlyinwardly along the cylindrical wall of the opening 34. As thecylindrical wall is provided with several slits 37, soap liquid isinjected into the tank thru said slits 37 through the slits 38 of thevalve box 16. After the bottom cover 19 is screwed onto the casing 18,the terminal plug of the electric cord is put in the plug socket and theswitch 24 is pushed into the body of the latherer, whereby the rotor 9is rotated by the motor 13 and the soap liquid flows into the stirringchamber from the tank 15.

The soap liquid in the stirring chamber moves toward the top nozzlealong the inner wall of the stirring chamber by means of centrifugalforce while being stirred with the helical blade 10. However, as theannular ridge 7 is provided on the terminal portion of the cylindricalwall 6, the soap liquid which is not thoroughly lathered and is flowingdown along the inner wall of the stirring chamber is blocked by theannular ridge, thereby enabling the soap liquid to become fully latheredand also preventing the unlathered soap from dripping from the nozzle.

The stirring of the soap liquid causes the volume thereof to expand andfully lathered soapsuds spout from the nozzle hole 3 through theclearance 11 due to the expansion pressure of the expanded volume of thelathered soap. The clearance modifies the spouting pressure of thesoapsuds and makes it uniform, and thereby soapsuds are evenly spoutedfrom the nozzle. Since the terminal edge of the nozzle has a concaveshape the soap can flow out from the nozzle smoothly even when thelatherer is being directly applied to a users face.
